[0021] In addition, some media, such as silicone grease, can also be filled into the internal cavity of the honeycomb cell to improve the heat dissipation effect.

[0022] Optionally, the honeycomb cells are composed of sheet materials, which may be metal parts. Of course, in some cases, they may also be cardboard; of course, they may also be polymer materials such as plastics and resins.

[0026] like Figure 2 and 3 As shown, as an embodiment, the second hexagon 4 includes a fifth side 41, and the length of the fifth side 41 is equal to the side length of the first square 1. The two fifth sides 41 in the two second hexagons 4 are connected to the first square 1 and the second square 2 respectively. Since the length of the fifth side 41 of the second hexagon 4 is equal to the side length of the first square 1, the circumference of the honeycomb cell is a closed structure to avoid gaps, so as to further disperse the in-plane load.

[0027] Optionally, the second hexagon 4 further includes a sixth side 42 , and the sixth side 42 corresponds to the fifth side 41 .

[0028] like Figure 2 As shown, as an embodiment, the second hexagon 4 also includes a sixth side 42, which is parallel to the fifth side 41, and the distance between the sixth side 42 and the fifth side 41 is equal to the length of the first square 1.

The first hexagon of one honeycomb cell can be connected to the second hexagon of another honeycomb cell, or it can be connected to the first hexagon of another honeycomb cell.

[0035] like Figure 7 and 8As shown, optionally, since the top of the honeycomb structure is an edge rather than a surface, in some cases, a portion of the top of the honeycomb structure can be cut along a parallel direction, so that the top of the honeycomb structure has a larger contact area.

[0036] Optionally, the honeycomb structure in the embodiment of the present application can be used in laptop computers to provide a heat dissipation structure; of course, in some cases, it can also be used in battery modules, where it can provide support, act as a buffer and protective layer, and also transfer heat.

[0037] like Figure 5 and 6 As shown, as an embodiment, the honeycomb cell includes two through-holes 7, the two through-holes 7 of any honeycomb cell are connected to the through-holes 7 of the other two honeycomb cells, and the remaining surfaces are connected through the corresponding surfaces of other honeycomb cells, thereby forming a multi-layer honeycomb structure, thereby improving the stability of the honeycomb structure.

[0038] Optionally, the remaining faces of the honeycomb cell are connected through corresponding faces of other honeycomb cells, which means that one side of the first square 1 of one honeycomb cell can be connected to the second square 2 of the adjacent honeycomb cell, and the first hexagon 3 can be connected through the first hexagon 3 or the second hexagon 4 of the adjacent honeycomb cell.

[0039] Optionally, two adjacent honeycomb cells may be glued together.

[0040] The following is combined with Figure 9 The implementation process of obtaining cellular cells performed by a terminal device provided in some embodiments of the present application is exemplified.

[0041] Please see the attached Figure 9 , attached Figure 9 A flow chart of a method for obtaining a honeycomb cell is provided for some embodiments of the present application. The method for obtaining a honeycomb cell may include: S910 , constructing a multi-layer Thiessen polygon seed, wherein the seed coordinates of the even layers in the multi-layer Thiessen polygon seed are obtained by offsetting the seed coordinates of the odd layers in the multi-layer Thiessen polygon seed according to the biased coordinates.

[0042] For example, as a specific example, a certain number of Thiessen polygon seeds are scattered layer by layer in the three-dimensional space to obtain multi-layer Thiessen polygon seeds.

[0043] For example, the seed coordinates for odd layers are:

[0044] The seed coordinates of the even layers are:

[0045] Where m and n are the seed Figure 10 The coordinates on the X and Y axes are shown. For example, p23 means that the seed is located in the 2nd column (X axis) and the 3rd row (Y axis). l Indicates the straight-line distance between the nearest seeds on the plane, and % is the remainder calculation.

[0046] From the above seed coordinates, we can see that there is a bias between the even layers and the odd layers. The specific relationship between the odd and even layers is as follows: Figure 11 As shown, the offset coordinate can be ( ). Figure 11 The arrow in the figure indicates the offset direction. In actual application scenarios, the offset coordinates can be adjusted as needed.

[0047] S920: Generate Thiessen polygons corresponding to the multi-layer Thiessen polygon seeds.

[0048] For example, as a concrete example, the following is generated by scipy.spatial.Voronoi() in Python: Figure 12 Thiessen polygons shown.

[0049] S930, solving the intersection between the Thiessen polygon and the preset size cube to obtain a honeycomb porous plate. For example, as a specific example, using a cuboid with a length, width and height of a*b*c (as a specific example of a preset size cube) to solve the intersection with the Thiessen polygon, the following is obtained: Figure 13 The honeycomb porous plate shown.

[0050] S940: Obtain the honeycomb cell based on the minimum repeating unit extracted from the honeycomb porous plate.

[0051] For example, as a specific example, the minimum repeating unit can be extracted from the honeycomb porous plate to obtain the preliminary extracted honeycomb cell. The extraction can be performed manually or using a related extraction algorithm, which is not specifically limited in the present embodiment. In order to ensure that the honeycomb structure is connected from top to bottom, the twelve-sided and connected minimum repeating unit, i.e., the final honeycomb cell, can be obtained by deleting one face on the top and one face on the bottom of the preliminary extracted honeycomb cell. Figure 14 shown.

[0052] Optionally, the deleted faces may be the two hexagonal faces at both ends of the honeycomb cell; of course, in some cases, faces of other shapes at both ends may also be deleted, but what is to be deleted are the faces at the ends of the honeycomb cell, not the faces in the circumferential direction.

[0053] As an implementation method, a Boolean operation is used to solve the intersection between the Thiessen polygons and the cube of the preset size to determine the honeycomb porous plate.

[0054] It is understandable that in addition to Boolean operations, other operations can also be used, and the embodiments of the present application are not limited thereto.
